You can put this solution on YOUR website!
The lines are parallel because they have the same slope.
How do I know this?
Look at the number next to x.
Any letter by itself means there is an "invisible" 1 there.
The slope of both equations is 1.
Since they have the same slope, the lines are parallel.
Understand?
